Abstract (en)
[origin: EP0694282A2] A method and system for detecting an incipient tumor in living tissue such as that of a human breast in accordance with differences in relative dielectric characteristics. A generator produces a non-ionizing electromagnetic input wave of preselected frequency, usually exceeding three gigahertz, and that input wave is used to illuminate the living tissue, being focused into a small, discrete volume within the tissue to develop a non-ionizing electromagnetic wave at that position. The illumination location is moved over a portion of the living tissue in a predetermined scanning pattern. Scattered signal returns collected from the living tissue are collected to develop a scattered return signal. The scattered return signal is employed to detect any anomaly, caused by differences in relative dielectric characteristics, that is indicative of the presence of a tumor in the scanned living tissue. <MATH>
